High diagnostic accuracy was achieved in both groups (98.3% vs 96.3%, respectively, for CAT vs non‐CAT; P = 0.6), comparable to the rates reported in prior studies (93%–96.1%),14;15;16 indicating that CAT did not significantly enhance the precision of CT‐guided CNB for diagnosing PNs. The gene discussed is CAT; the disease is paraneoplastic neurologic syndrome.
